WEP Keys ?

Couldnt Think Of Any Where Else To Ask This.

But I Forgot How You Can Sniff For The Key. I Havent Done It For A Couple Years Because My PSP Needed To Have It. But I Sold That, So I Completly Forgot How. Now I Need To Because My Neighbors Once Again Got Wireless, But Like D Bags, They Have A WEP, And My iPod Needs It.
